I watch The Simpsons in French and often I hear some informal expression, but I cant figure out how one writes them.
1) What a informal word for a tv set in French (like telly) ? Homer (main character) calls it like "téléch". How this word is written?
2) From time to time characters express their agreement with an expression that sounds like "ok, dack".
For example https://youtu.be/ohI1X6ynKH8
What he pronounces exactly?
